On one hand, I'd say that I doubt it... Guys like Mac Danzig, George Roop and Dan Hardy have proven that you don't have to win fights to stick around.
On the other hand, guys like DeMarques Johnson, Tamdan McRory and Rob Emerson have proven that even if you step up when the company needs you, you put on exciting fights and entertain the fans, you can get find yourself on the receiving end of a head-scratching cut from the promotion.
In short, who the hell knows?
